IVO MARCHETTI, GF BOS'IQN, MASSACHUSETTS.

STOVE.

Application filed September 20. 1916.

To all whom it may concern Be it known that I, Ivo MARCHETTI, a subject of the King of Italy, residing at Boston, county of Suflolk, State of Massachusetts, have invented an Improvement in Stoves, of which the following description, in connection with the accompanying drawing, is a specification, like characters on the drawing representing like parts.

This invention relates to stoves and has for its object to provide a stove with a novel ash sifter by which the ashes may be sifted whenever the grate is dumped.

In order to give an understanding of my invention I have illustrated in the drawings a selected embodiment thereof which will now be described, after which the novel features will be pointed out in the appended claims. 7

In the drawings, Figure l is a front view partly in section of a stove embodying my invention; Fig. 2 is an end view of the stove with parts broken out to better show the construction; Fig. 3 is a detail hereinafter described.

The stove is indicated generally by 1 and it is provided with the usual fire box 2 and grate 3. These parts may have any suitable or usual construction. Situated beneath the grate is a chute 4L which has an inclined position and is pivotally mounted at its upper end to the sides of the chamber 6 beneath the grate, as shown at 7, said chute being positioned to receive the ashes and coal that are dumped from the grate 3. The chute is provided with a lug 9 which normally rests on a shoulder 10 formed on the stove, the shoulder being positioned to support the chute in the inclined position illustrated in Fig. 2. .The lower end of the chute is provided with a discharge spout 8 through which the contents of the chute can be discharged into an ash sifter situated beneath said chute. This ash sifter is of the rotary type, it comprising a cylindrical sieve-like member 11 connected at its ends to two spiders or skeleton heads 12 and 13. This rotary ash sifter is sustained on a shaft 14: mounted in suitable bearings 15 and 16 formed in the stove. Said rotary ash sifter inclines in the opposite direction from the chute 4 and is adapted to receive the material delivered from the discharge spout 8.

In order to direct the material from the discharge spout into the sifter 11, I have provided an apron or deflector 160 which Specification of Letters Patent.

Serial No. 121.294-

is semi-circular in cross-sectional shape and is situated beneath the discharge spout 8 and passes into the upper end of the sifter 11. This deflector 160 directs the material delivered from the spout 8 into the ash sifter. When the ash sifter is rotated about its axis, the ashes will be sifted thereby and the lumps of coal which cannot pass through the sifter will gravitate toward the lower or right-hand end of the sifter and will be delivered therefrom.

I have provided two pans or receptacles 17 and 18, one to receive the ashes and the other to receive the coal and other larger lumps. The receptacle 18 for receiving the coal is situated in the chamber 6 beneath the lower end of the ash sifter and the receptacle 17 is situated underneath the upper end of the ash sifter. In order to direct the ashes into the receptacle 17, I provide two deflecting aprons 19 and 20, one situated beneath the upper end of the sifter and the other beneath the lower end thereof and both directed toward the receptacle 17.

The shaft 1% of the sifter 11 projects through the front of the stove and is provided with the non-circular portion 21 to which a handle may be applied for rotating the sifter. I have also provided means for jogging the chute 4 by the rotary movement of the sifter so as to insure that the material will be shaken out of the chute as the sifter is rotated. This jogging means comprises a cam 22 carried by the sifter and adapted to engage a projection 23 on the underside of the chute 4:. The cam member 23 is formed on a spider-like element 2a which is situated within the sifter 11 and the cam 22 projects through the sifter in position to engage the projection 23. With this construction it will be observed that at each rotation of the sifter the chute 4 will be jogged, and this vibratory movement of the chute will insure that the material therein will be delivered through the discharge spout 8.

The end of the stove will be provided with suitable doors or openings through r the chute to the ash sifter, means to vibrate the chute by rotation of the ash sifter, and two receptacles situated beneath the ash sifter and adapted to receive the ashes and the 1 coarse material, respectively.

2. In a stove having the usual grate, the combination with an inclined Vibratory chute situated beneath the grate to receive material dumped therefrom, of a rotatable cylindrical ash sifter situated beneath the chute, means to direct the material from the chute to the ash sifter, means to vibrate the chute by rotation of the ash sifter, a receptacle situated beneath the lower end of the ash sifter to receive the coarse material delivered therefrom, an ash-receiving receptacle, and deflecting aprons to deflect into said ash-receiving receptacle the ashes that are sifted through the sifter.

In testimony whereof I have signed my name to this specification.

IVO MARCHETTI.
